6. The graphic shows the continents of the world and traces the route in which cholera spread in recent outbreak years. In general, the disease travels along continental edges, around Africa in the mid 1960s and 1970s; in Oceania and Southeast Asia in the early 1960s, 1970s, early 1980s, and 1990; the Middle East and Eastern Europe in the mid 1960s; Central and South America in 1991; and the Gulf of Mexico in 1973.

9. This graph plots the number of Vibrio cholerae found associated with Copepods in Bangladesh, from 1987- 1992 – the detection was by Fluorescent Monoclonal Antibody methods. The plot shows peaks for Juveniles, Adults, and Nauplii in April; smaller Adult and Juvenile peaks in June (but a much larger Nauplii peak); a small Juvenile peak and a very large Nauplii peak in August; and small Adult and Juvenile peaks in November when there was another very large Nauplii peak.

13. Schematic diagram contrasting old and new approaches to epidemiology. Old static triangle labeled at its three points with: environment, agent, host. New triangle- shaped diagram, with interactive vector arrows pointing among all points, has labels: between environment and agent, are longevity and infectivity, distribution and transport, altered selective pressures; between agent and host, are tissue tropisms, pathogenicity, immune response, and host specificity; and between host and environment are nutrition, hygiene, treatment, and housing Ecosystem Change and Public Health: A Global Perspective, Chapter by Mark L.
